Back Pressure Regulators

Our range of Alicat pressure controllers is available with single or dual valves. They can be used in standard, vacuum, differential, closed loop and closed volume pressure applications.

The Alicat PC series range of pressure controllers have single control valves with different valve options dependent on your application.

The Alicat PCD series are dual valved pressure controllers. All pressure controllers are available with a remote pressure sense port should your process require it.

The PC and PCD series pressure controllers from Alicat are also available for more aggressive applications featuring all 316 stainless steel wetted parts and FFKM seal options.

Every single pressure controller from Alicat features an analogue output signal as well as RS232 data communications.

We have a complete range of mass flow controllers which allows us to cover a large range of flow rates. From the smallest mass flow controller, which is capable of controlling flow rates from as little as 0.00025 SCCM (Standard Cubic Centimetres per Minute), up to our largest mass flow controller, which can control up to 5000 SLPM (Standard Litres Per Minute).

Alicat Scientific’s mass flow meters provide precise measurement solutions for a wide range of gases and gas-based processes across numerous industries. Designed to automatically compensate for changes in pressure and temperature, they deliver both mass flow and volumetric flow readings—offering exceptional accuracy and adaptability for diverse applications.

Our selection includes models to suit almost any requirement. The standard M Series handles the majority of use cases, while specialised options are available for portable operation, corrosive gas handling, ultra-low pressure drop scenarios, and on-the-go calibration.

Each unit comes equipped with a clear local display and intuitive keypad for straightforward configuration, along with analogue output and RS-232 digital connectivity (additional communication protocols available). Every model supports measurement of over 80 gases and gas mixtures, with the flexibility to add custom gases. Users can also fine-tune readings by adjusting for fluid density, ensuring highly precise mass flow measurements every time.
